Function
function
Involved in the catabolism of short chain fatty acids (SCFA) via the tricarboxylic acid (TCA)(acetyl degradation route) and probably the 2-methylcitrate cycle I (propionate degradation route). Catalyzes the reversible isomerization of citrate to isocitrate via cis-aconitate. Could catalyze the hydration of 2-methyl-cis-aconitate to yield (2R,3S)-2-methylisocitrate. The apo form of AcnA functions as a RNA-binding regulatory protein.
Catalytic activity
- citrate = D-threo-isocitrate
Cofactor
Note: Binds 1 [4Fe-4S] cluster per subunit.
Pathway
Carbohydrate metabolism; tricarboxylic acid cycle; isocitrate from oxaloacetate: step 2/2.
Organic acid metabolism; propanoate degradation.
